I have a O3DSXL with OFW 8.1.0-11u I need to know a few things first 1. I want to play 3ds backups I hear it's got to be .cia format, is there a way to do this with a .3ds file or does it convert automatically? 2. I want to play DS games and GBA would I be able to do this on cfw? 3. Do I use rxtools or cake/pasta/X to get cfw? 4. How hard is it to install cfw and adding my games and can I do this without an internet connection on the 3ds? 5. What SD card should I invest in holding all of the games by the sound of it 64gb should be the limit no? 6. Does having sky3ds (blue button) make getting cfw any easier?
